Probably better to do this on the endpoints themselves. Your phone should have the ability to provision volume, gain, etc. Whilst it might work for your current setup, a firmware update or new handset or client might have people getting their ears blown off. You might also see some nonsense with DTMF tones not registering properly.

Note
In digital audio it is not optimal to modify the audio stream at the server level. It is almost always better to adjust the volume at one of the analog points, like the phone, headset, or analog TDM card. This dialplan application is available to assist the user who has broken devices that can't or won't adjust their audio.

If you really need to do this, I should expect you'll need to insert it into the dialplan in the Dialplan Manager where it's necessary. I haven't tested it, but I suspect you might be able to do this pretty high up in the ordering with a new rule to apply to everything on the system.

I solved it by amplifying the audios with audacity
